October 2015 finishes warm & wet

By Rod Hill on 2015-11-02


Saturday's six hours of heavy rainfall, dropping 1.97" at PDX, put Portland over the top for the month of October with total rainfall of 3.69 inches.  Normal for the month is 3.00 inches.  The wet finish to the month snaps a dry stretch of below normal precipitation for consectutive months that began back in April. (If you are wondering, the wettest Halloween on record was back in 1994 when 2.44" fell at PDX and downtown Portland got drenched with 2.68 inches of rain!)

October also made news for warm temperatures.  The monthly mean of 60.1 degrees, ties October 2014 for the warmest all-time!  The average high, average low and mean temperatures were all 5 degrees above normal!  All but three months this year; January, April and September have finished as top five warm months in either low temp, high temp or the mean.  September stands alone as the only month of 2015 to average below normal temperatures. 

Outlooks give November a chance of seeing normal rainfall, which would be 5.63 inches.  November is typically Portland's wettest month of the year!  Temperature outlooks call for warmer than normal days to continue.
